Isadora 1.3.1f06 no
Hi,for me the threaded movie playback is not working with IsadoraCore 1.3.1f06 on OS 10.9.1, playing Pro Res 4:2:2 HQ movies.Working fine on IsadoraCore 1.3.0f24.BestLoïc
if you look at the release notes for 1.3.0F06, you'll find this:***IMPORTANT*** Turn off threaded movie playback. It is no longer recommended.
Yup, read that after burning my headMy badsThanks @dbini
